Success and here’s how it happened. Please note that I take no credit and I’m going to list the steps as I recall executing them that yielded the successful results. I’m posting this only as aid to those like me that have been working for some time trying to get the Zotac 9500GT 1GB GDDR2 PCI Express 2 card fully working under SL 10.6.3.
Base system:
Gigabyte EP45-UD3L
Intel E2180 2.0 GHz Processor
4 GB of DDR2 667 MHz Memory
250 GB Sata Harddrive
Lite-On DVD Drive
I’ve updated the bios on the motherboard to the Cartri modded Bios version 0.7m.
I’m running SL 10.6.3 with all updates available as of 4/15/10.
I’m running Chameleon 2.0-RC4 bootloader. (myHack_Installer_1.0)
In my “/Extra” folder are the following:
com.apple.Boot.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

Extensions.mkext
/Extensions
/Themes (installed and used by bootloader)
Also of interest I’m sure, are the contents of my “/Extra/Extensions”:
FakeSMC.kext
HDAEnabler.kext
OpenHaltRestart.kext
Orangeconfix.kext
Going into tonight, I had everything as described above and two extra files in the “/Extra/Extensions” folder. I had NVInject.kext and NVEnabler 64.kext in the folder. When I’d boot into SL in 64bit mode, I had the same problems as everyone else. My video card was recognized as a Nvidia 9500GT with 1GB of memory and had all resolutions available but no QE/QI.
Tonight I stumbled upon a newsgroup discussion where someone listed a terminal command for enabling Quartz GL in Snow Leopard:
$ sudo defaults write /Library/Preferences/com.apple.windowserver QuartzGLEnabled -boolean YES
The author then says that he modded his DSDT and removed all NVInject and NVEnabler kext and rebooted and his 9500GT now had QE/QI enabled.
Well, since I’m using a modded bios that removes the need for a DSDT file I was unsure whether this method would work but what the heck, I’ve tried all else why not this.
I open a terminal and ran the Quartz GL enabling command above.
I deleted all the NVxx kexts from /E/E.
I ran “Kext Utility” and repair permissions on Extensions and rebuilt the Extensions.mkext files
I crossed my fingers and rebooted my system.
The first reboot was not totally successful. I arrived at desktop with some minor distortion and a frozen cursor. I shut down and restarted the system and the second boot was perfect, right to desktop. First thing I did was look at the Graphics/Display information and here’s what I found:
GeForce 9500 GT:
Chipset Model: GeForce 9500 GT
Type: GPU
Bus: PCIe
Slot: Slot-1
PCIe Lane Width: x16
VRAM (Total): 1024 MB
Vendor: NVIDIA (0x10de)
Device ID: 0x0640
Revision ID: 0x00a1
ROM Revision: xx.xx.xx - internal
Displays:
HF229:
Resolution: 1680 x 1050 @ 60 Hz
Pixel Depth: 32-Bit Color (ARGB8888)
Main Display: Yes
Mirror: Off
Online: Yes
Rotation: Supported
Display Connector:
Status: No Display Connected
The only difference I saw was my ROM Revision was now showing “xx.xx.xx - internal” Before it was showing something related to NVInject.
I then opened up Dashboard, added a Widget and got the “water effect”.....SUCCESS! QE/QI appears to be working. I then opened a jpg image with Preview and it displayed the image. I opened Front Row and played a movie preview. I even ran XBench and all the video tests completed successfully!
I hope this helps someone working on the Zotac 9500GT 1GB... it will fully function under 10.6.3.
PS: I know someone is going to ask so here’s the answer. My monitor is connected to the vga output on the video card. I’ve not tested any of the other video outputs on the card.

Just wanted to expand the list of ASRock boards now successfully running SL to include the Wolfdale 1333-D667 R2.0 thanks to this thread. My full specs include an Intel E2180, 4 GB of DDR2 667, 250 GB Seagate sata drive, Lite-On dvd drive. I'm currently running the onboard GMA 950 but have a BFG 9400 GT with 512 MB of memory waiting to be installed. Oh yes, the built-in lan (RTL8169E) works with driver I use with Leopard 10.5.7 (32 bit mode only). The built-in audio ALC662 works with AppleAzaliaAudio.kext (provided in one of the posts in this thread). Thanks again for sharing your experience.
